To all whom it may concern:

Be it known thatI, HERBERT H. RoosA, of Lincoln, in the county ofLancaster and State of Vebraska, have invented certain new and usefulImprovements in' Clamping Devices for Shoe-Heels; and I do hereby r thereference-numerals marked thereon.

declare the-followingto be'a full, clear,and

exact description of the same, reference being had to the accompanyingdrawings,

forming a part of this specification, and to My invention has for itspurpose to providev animproved clamping device, to be used in gluing orcementing high heels, French heels, or any wooden heels to boots,

shoes, slippers or pumps.

' of the heel and against the heel seat, so as p 1 vide a structure witha, minimum number of parts, simplifying. the operation and reduc- Anespecial object of my improvement is to afford a clamping device soconstructed that the pressure or clamping action 'will be distributedevenly over the entire bottom to avoid concentration of theclampingaction at one portion of the edge of the heel, such as occurs ifthe ordinary type of parallel jaw clamp is employed. a

A further purpose of my improvement is to provide a device readilyadaptable to heels of different sizes, such a manner that the clamp willaccommodate itself to heels of different pitch, andalso to affordto theoperator unobstructed view ofthe base of the heel, and the heel seat,andample space to beat up and mold the heelaseat. 1

Still an additional object, is to afford a portable device such thattheshoe can read ily be subjected to various finishing operations with theheel clamped inposition, thus permitting the cement or glueto set whilevother work is being performed upon the shoe.

Another object of the invention .is'to pro- "ng the manufacturing cost,andin arranging the parts so as not to interfere with or damage the shoeupper, or crush or deface the heel whilethe parts are in clampedrelation. To these and other ends the invention consists in certainimprovements and combinations of parts" all as will be hereinafter morefully described, the'novel featuresibeingpointed out in the claims.at'the lend of the specification;

Similar,reference: numerals in the several figures indicate the sameparts.

There are various ways in which the invention may be carried outpractically, and for the purpose of this application I have illustrateda preferred way of-its accom i plishment byway of example, and it willbe understood that it is not intended to confinev the invention to-theparticular structure shown. Referring to Figs. 1 to i, 1 designates abase whichin this instance constitutes the last support and is providedwith a last engaging pin 2 held in place by a ,set screw 5,.and arrangedtohold a last with a shoe upper thereon, as usual in. this art.

Pivotally mountedinpon the last support is aLcla-mp carrier, preferablyembodying guide rods 3 having inturned lower extremities which.engage-bearings 4 in the .last support carrier upon theguide rods. Theclamp '6 1. The guide rods 3- are connected at their i upper ends by aCross head 8 which is. retai-ned in fixed relation to the guide rods, by

enlargements 10 1112011 the latter, which arel is provided with aclamping surface 16 i.

which isinclined with reference to aplane perpendicular to the generalvdirection of clamping action. The inclined clamping surface16fpreferably extends fromone end ofthe clamp to the other, andisarranged so as to conform to the inclination of the bottom of a Frenchheel or high heel such as used on ladies shoes, with reference to' theheel seat.

As the, heels become larger and lower, the

inclination of the bottom of the heel becomes less, or in other words,the bottom of'the heel becomes more nearly parallel to the heel seat,and this is provided" for in the present structure by the pivoting ofthe clamp carrier which can be swung around I the last support, asindicated by dotted lines a in Fig. 1.

As the clamp is thus moved laterally, its inclined clamping surface 11becomes more nearly horizontal, thus conforming to the bottom of a heelwhich is larger or lessinclined than the extreme French heel. i

The clamping surface 16 terminates in a shoulder 17, which engages therear edge of the heel and assists in positioning the parts; 7

When in clamped position, the surface 16 engagesover substantially theentire bottom of the heel, and the pressure is thus distributedthroughout the heel. This aifords'a'n even engagement between the heeland its seat, thus more securely attaching the parts,

and it also obviates the danger of creasing or defacing the covering ofthe heel or otherwise damaging the heel, as when the pressure isappliediat its one edge only, causing greater compression through oneportion of the heel than another. 7 The clamp is actuated by a clampingscrew 7, which is threaded in an opening 12 of the cross head 8, andis-provided with an operating handle 9. The operation will be readilyunderstood and consists in positioning a last, with a shoe upper andsole thereon, upon the last engaging pin 2, and after the heel issupplied with glue or eement and properly positioned upon the shoe seat,the

' clamp 6 is brought down upon-the bottom 0f'the heel.' The clampcarrier is adjusted aboutits pivotal axis until the clamping surfacecorrectly conforms to the inclination of the bottom of the heel,'and theclamping screw 7 is then tigh In some cases it is quite desirable toperform other work on theshoe'with the heel clamped thereon, and forthis purpose I pro-.

vide'the mechanism shown in Figs.5 to. 8 inclusive. In this form,-instead of using a large base, such as shown 1n Figs. '1 and 2 for thelast support, I employ a last support 13 upon which the guide rods 8 ofthe clamp carr er are'pivoted in sockets 14. 'The last support 13 isprovided with a central opening 15 to temporarily receive a' last"pin.2,

while the heel is being clamped to theshoe'.

The operation and remaining parts are the I same as alreadydesoribed,and afterthe heel isclamped, the entire structurev can be reinoved'fromthe last pin 2. This arrangement affords a light,"p ortable device thatcan be readily carried to permit other finishing operations upon theshoe while the glue under the heel is hardening. r V v The last support13 is cut away slightly .uponits upper surface at opposite sides of Ythe center part, as indicated atfl-S The purpose of this is to provide aslight clear ance between 'the last and the end portions 1.
